The Development of Auto-cascade Refrigeration;

According to the simulation results of -40℃ freezer with autocascade refrigeration system using zeotropic refrigerant mixture of R744/R717, the feasibility of this system on how to deal with temperature change of cooling media and avoid superheat of compressor is investigated after analyzing system characteristics under various operating conditions.

Based on related program, the tunning parameters of classical cascade cycle and that of autocascade cycle on different conditions ate calculated,and then the running characteristics of the two cycles are compared,which may help the further research on autocascade cycle.
